13 Claims. The present invention relates to improvements in highway markers, and more especially to ma-- chines to marking traffic guiding lines on highways as the machine travels thereon.

One of theprimary objects of the invention is to provide a novel and improved machine of this class which comprises a vehicle adapted to travel along the highway and a painting machine connected thereto to travel therewith and carrying means for painting a traflic guiding line on the pavement or surface of the highway as the vehicle advances, means being provided for steering or setting the course of the painting machine relatively to that of the vehicle to conform with curves of different radii in the highway and to thereby enable the traflic guiding line to be applied to the center of the width of the highway at curves therein as well as along straight portions thereof.

Another object is to provide a sanding device cooperative with the painting machine for applying sand to the painted traffic guiding line immediately after the painting thereof, thereby covering the same and thus preventing picking up of paint therefrom and spreading thereof upon other portions of the'pavement or surface of the highway by the wheels of vehicles crossing the traffic guiding line after the same has been painted and before it is dry.

Another object is to provide novel and improved means for applying the paint to the pavement or surface of the highway whereby the traflic guiding line may be made of different widths as desired, the marginal edges of the painted line will be sharply defined, and splashing or dropping of paint beyond the margins of the painted line is prevented.

A further object of the invention is to provide the vehicle to which the painting machine is attached with steering means located to be operated by the attendant while in a position where an edge of the highway is visible so that it may serve as a gauge for the steering of the vehicle in a course along the highway which will insure the painting of the traflic guiding lines in proper position thereon.

To these and other ends, the invention consists in certain improvements and combinations and arrangements of parts all as will be hereinafter more fully described, the features of novelty being pointed out particularly in the claims at the end of the specification.

Similar parts are designated by the same ref- 3 erence characters in the several figures.

The preferred embodiment of the invention is shown in the accompanying drawings and will be hereinafter described in detail but it is to be understood that the invention is not restricted to the precise construction shown since equivalent constructions are contemplated and such will be included within the scope of the claims.

In the present instance, the invention is shown applied to a highway marker of the same general class as that shown and described in Letters Pat- 40 ent No. 1,763,432, granted June 10, 1930, it however providing improvements thereover, as will hereinafter appear.

The improved highway marker comprises generally a vehicle, preferably a motor truck or other appropriate automotive or self-propelled vehicle and a painting machine for painting the trafflc guiding lines, the painting machine having means for attaching it to the vehicle so that it will be drawn thereby and will be appropriately guided or steered, and in some instances where such is desired or required, a sanding device is provided to cover the freshly painted traflic'guiding line with sand and thereby prevent tracking of paint 5 therefrom onto other portions of the pavement of the highway.

The vehicle shown in the present instance comprises an ordinary motor truck having a frame or chassis I, front and rear wheels 2 and 3, the front wheels being pivoted to the front axle as usual and provided with steering means controlled by the ordinary steering wheel 3, as in an ordinary motor truck. However, for the purposes of the present-invention, the motor truck is provided with an auxiliary steering gear 4 for' the front wheels 2, this auxiliary steering gear being controlled by an auxiliary steering wheel 5 which is mounted at the right hand side of the truck, an auxiliary seat 6 being provided which an attendant may occupy for manipulation of the auxiliary steering wheel, and the right hand front fender 1 which usually shields the right hand front wheel of the ordinary truck is hinged on a horizontally extending hinge pin 8 toward the inner side of this fender so that the latter may be swung upwardly and inwardly toward or against the hood 9 of the truck and thereby expose the right hand front wheel of the truck and also the right hand edge of the pavement of the highway to the attendant occupying the seat 6 and controlling the auxiliary steering wheel 5 so that this attendant may guide the truck by the auxiliary steering wheel 5 so as to cause the right hand front wheel 2 to travel along the right hand edge of the pavement of the highway and thus utilizing this edge of the highway as a gauge to position the painting machine attached to the left hand side of the truck, as will hereinafter appear, centrally of the width of the highway. A catch l may be provided for retaining the hinged fender 1 in its lowered normal position during thetravel of the truck when the painting machine is not in operation.

The truck is also provided with a suitable body I I on which are mounted a suitable number of paint supply tanks, two of these tanks l2 being shown in the present instance, and the truckbody also carries a compressed air supply tank I3, the latter being provided with an air compressor l4 for supplying compressed air thereto, this air compressor being preferably driven by an internal combustion engine l5 which is independent of the engine which propels the truck. The truck body is also shown provided with a rotary or other suitable and well known type of pump I6 which may be belted to or otherwise driven from the engine I5, this pump having an inlet l1 adapted to be connected by a hose or otherwise to paint drums or receptacles containing a supply of paint and the pump is connected by a pipe l8 to the paint supply tanks l2 whereby the pump may be used to fill these paint supply tanks on the truck from paint containing drums or other receptacles. The paint supply tanks l2 may be provided with agitating devices therein for maintaining the paint in properly mixed condition, as for example is shown in the above noted patent, and such agitating means may be driven in any suitable manner, as by compressed air motors I9 which may be mounted on the tops of these tanks. The paint, in liquid condition, is conducted from the supply tanks I 2 through a flexible hose 20, and compressed air is supplied from the tank I 3 through a flexible hose 2|.

Y The painting machine according to the present invention comprises a main frame. 22 which is preferably yoke-shaped in form to provide side arms 23 the rear ends of which are bent downwardly to form substantially upright side members 24, the side members of the frame being bent toward one another at the front and rigidly secured together by a head 25. The lower portions of the upright frame members 24 have alined axles 26 projecting outwardly therefrom and sup- 5 porting wheels 21 rotatably mounted thereon, these wheels preferably having pneumatic tires to absorb shocks due to unevenness in the highway surface. Vertical guides 28 are fixed to the inner sides of the upright frame members 24 and i0 slides 29 are individually movable vertically in the respective guides, each of these slides having a shaft 30 rigidly secured thereto near its lower end and projecting inwardly therefrom, these shafts being preferably located in the same vertical plane with the axles 26, and circular paint confining disks 3| are rotatably mounted on the respective shafts. Springs 32, each attached at one end to the respective guide, as by a book 33, and at its other end to the respective slide, as by an adjustable screw eye 34, serve to individually force the respective disks downwardly relatively to the frame of the painting machine, and thereby maintain said disks in rolling contact with the surface of the highway or pavement, the individual vertical movements provided for these disks enabling them to remain in contact with the highway surface notwithstanding unevenness thereof.

The painting machine frame also comprises a cross member which connects the side arms 23 thereof rigidly and thus maintains them in fixed laterally spaced relation, and the frame also comprises horizontal side members 36 which are rigidly secured to the outer sides of the up- 35 right members 24, these side members being rigidly connected by front and rear cross members 31. The disks 3| are shiftable axially on their respective shafts 30 so that the distance between these disks may be varied to conform with the 40 painting of lines of different widths. The distance between the disks and, accordingly, the width of the line to be painted on the highway, is controlled by suitable means, preferably by rollers 38 carried by posts 39, a pair of these rollers and posts being preferably provided at the outer side of each disk, and the postsare supported adjustably on; the respective horizontal side members 36 of the frame by screws 40 which enable the rollers ,to be adjusted toward and from the respective side members 36, and lock nuts 4| on the respective screws serve to lock the posts 39 and the rollers 38 in different adjusted positions.

Means is provided for removing from the inner sides of the disks surplus paint that may adhere thereto, thereby preventing splashing or dropping of the paint on the highway surface beyond the margins of the line painted thereon. As 'shown in the present instance, a paint collecting trough 42 is attached by a bolt 43 to a bracket 44 which latter may be attached to the rear cross member 31 of the frame, this trough having a pair of branches 45 which diverge so that they are in contact at their outer edges with the inner surfaces of the respective disks 3|, these branches of the trough thus serving to scrape surplus paint from the inner sides of the disks and to cause the paint thus removed to flow by gravity through the trough, and the trough may be provided toward its rear end with a hook 46 upon which a bucket or other suitable receptacle 4'! may be hung so that it will receive and collect the surplus paint removed from the disks by the trough. The width of the disk-engaging portion of the trough con- .which extends between the lower edges of the disks, is performed by a paint gun 48 which may be of any suitable or well known construction having valve controlled paint and compressed air supply connections 49 and 56 which are connected to the respective flexible hoses 26 and 2|. The paint gun is supported in suitable position between the disks 3| by an arm 5i which is rigidly attached to and extends downwardly from the cross member 35 of the frame. Preferably, the paint gun is so supported that it may be adjusted vertically and thus position its nozzle at the proper elevation above the highway surface to effectively apply and distribute the paint thereon, the paint gun being mounted for this purpose on a slide 52 which is movable substantially vertically on a guide 53 fixed to the supporting arm 5|, and a screw 54 to which a handle 55 is attached, serves to adjust the slide 52 and the paint gun connected thereto on the guide 53, the screw in the present instance being threaded in a bracket 56 which supports the guide 53 on the arm 5|.

The painting machine is attached to the inner or left hand side of the truck so that it will be drawn thereby, and the attaching means pivotally connects the painting machine to the truck so that the course steered by the painting machine will conform with the course of the truck or vehicle as the latter advances along the highway and especially while the truck or vehicle is traversing a curve in the highway, so that the traffic guiding line will be painted in the center of the width of the highway, on curved as well as upon straight portions thereof, and the attachment between the painting machine and the truck or vehicle includes a universal joint which enables the painting machine, riding on its supporting wheels, to accommodate itself to unevenness or irregularities in the surface of the highway. As shown in the present instance, such attaching means comprises a bracket 51 having arms 58 pivoted at their extremities to square blocks 59 adapted to fit between the out-turned flanges of vertical angle irons 60 bolted or otherwise secured to the inner or left hand side of the frame or chassis of the truck, and bolts 6| serve to secure the blocks 59 between said angle irons and to pivotally connect the blocks 59 to the respective arms 58 of the bracket, the blocks 59 having ledges 59 on which the arms 58 may rest when the bracket is lowered so that the bracket will be supported in its operative position so that it projects substantially horizontally and laterally from the inner or left hand side of the truck. When the paintingmachine is not in use and the truck is being moved from one place to another, the bracket 51 may be swung upwardly about the pivot bolts 6|, into upright folded position against the adjacent side of the truck where it may be held by any suitable means, so that it does not then form an obstructing projection therefrom. The bracket 51 has a bar 62 secured thereto as by clamping screws 63, an end of this bar extending beyond the bracket and having a downwardly offset portion 64. The

4 which is slidable longitudinally of the draft bar painting machine carries a draft bar the'forward end of which is provided with means for connecting it to the portion 64 of the bar 62, such connecting means preferably embodying a joint which permits universal movement of the bar 65 and the painting machinerelatively to the bar 64, and this connecting means is also adjustable along the bar 64 to vary its distance laterally beyond the side of the truck and thereby provide for the painting of traffic lines centrally between the edges of highways of different widths. Such connecting means as shown comprises a slide 65 which is adjustable longitudinally of the bar 64 and is provided with a set screw 61 for firmly clamping it in different adjusted positions there- 15 on. The slide 66 is formed with a circular hub 68 on which a ring 69 is mounted rotatably so that it may rock or turn on a horizontal axis, and the draft bar 65 is apertured at or near its forward end to rotatably receive a pivot pin 10 which 20 is fixed on a vertical axis in the ring 69, a nut 1| threaded on this pivot pin servingto retain the bar 65 in engagement therewith. The construction just described enables the draft bar 65 for the painting machine to be placed in different po- 25 sitions on the bar 64 and hence spaced at different distances inwardly from the inner or left hand side of the truck, and the rotatable ring 69 and pivot pin 10 enable the draft bar 65 to swing horizontally to conform with different courses steered 39 by the painting machine relatively to the course of the truck and to swing vertically to conform with unevenness in the surface of the highway. The frame 22 of the painting machine is connected to the draft bar 65 by a draw bar 12 which is preferably slidable longitudinally in the head 25 and is provided with a coiled compression spring 13 which bears against the rear side of the head 25 and against a collar 14 fixed on the draw bar -so that sudden or uneven pulling of the draw bar 12 will be absorbed or cushioned-by the spring 13 and hence jerking of the painting machine from such cause will be avoided. The draw bar 12 is preferably circular in cross section so that it is swivelled or rotatable on a horizontal longitudinal axis in the head 25, such swivelling permitting the painting machine to rock laterally as its supporting wheels at the opposite sides thereof ride over uneven portions of the highway surface. The forward end of the draw bar 12 is operatively ccnnected to the draft bar 65 by a bracket 15 one end of which is pivotally connected to the draft bar so as to rotate relatively thereto, on a vertical axis, by the pivot stud 16 and the other end of said bracket being pivotally connected to the draw bar 12 by a joint having a vertical pivot pin 11.

Means is provided for setting the painting machine in different angular positions relatively to the draw bar 65 so as to cause the painting machine to steer a proper course to apply the traflic guiding line in the center of the width of a curve in the highway, such means comprising a locking segment 18 fixed to posts 19 attached to the rigid cross member 35 of the painting machine frame, and a locking dog 80 65 in a guide 8| thereon and having a releasing grip 82 connected thereto by a rod 83, this dog being engageable in one or another of suitably arranged notches 84 formed in the segment 18. 7 Preferably, the notches 84 in said segment are spaced or graduated therein in accordance with the different degrees of curvature of the curves in highways so that by setting the dog in the proper notch in the segment, the painting machine will be set to steer a course which will insure painting of the traffic guiding line midway of the width of a correspondingly curved portion of a highway. The locking segment I8 is concentric with the vertical pivot I which connects the draft bar 65 to the frame of the painting machine, and lateral swing of the draft bar 65 in either direction, and which will shift the pivot 16 in a corresponding lateral direction with respect to the pivot pin 19, will set the painting machine and its supporting wheels 21 which ride upon the surface of the highway in diiierent angular positions relatively to the draft bar 65 and will thereby alter the course steered by the painting machine as the same is drawn forwardly by the pivot pin I9, the rear end of the draft bar 95 being swung toward the truck or vehicle when the curve in the highway to be traversed curves toward the left, and the draft bar being swung away from the truck when the curve in the highway curves toward the right, the supporting wheels 2! of the painting machine being thus directed either toward or away from the truck or vehicle in order to cause the painting machine to traverse a course centrally of the width of the highway when a curve therein is being traversed. The rear end of the draft bar 65 is provided with a handle 85 to facilitate its manipulation to thus control the steering of the painting machine. A seat 86 is provided which may be occupied by an attendant for the painting machine, this seat being supported on a link 81 which is connected by a vertical pivot bearing 88 to a second link 89, and the latter link is connected by a vertical pivot bearing 99 to the rear end of a link 9|, the latter being pivoted by a horizontal pivot pin 92 to a bracket 93 fixed to the adjacent side of the truck or vehicle and the latter having a bar I 94 fixed at or toward its rear end to underlie the link 9| and thereby provide a support on which it may rest. While the link 9| rests on the bar I94, the links 81 and 89 will be supported to swing in a substantially horizontal plane about the vertical pivots 88 and 99 as centers, thereby enabling the seat 86 to be swung either forwardly or rearwardly or laterally in either direction so that it may occupy the proper position at the rear of the painting machine to enable the attendant occupying the seat to reach and manipulate the painting machine while the vehicle and painting machine are in operation. When the painting machine is not in operation, the link 9I may be swung upwardly about its pivot 92 and the links 81 and 89 and the seat 86 attached thereto may be swung inwardly into or above the truck body so that they do not then form obstructions at the side of the truck.

Preferably, and as shown, the pivot pin I9 from which the painting machine trails, is located at a side of the truck or vehicle in substantial alinement with the axis ofthe rear wheels 3 thereof, as will be clear from Figs. 1 and 3, with the resulting advantage that the course of the trailing painting machine will be subject to minimum lateral deviation incident to lateral deviations in the course of the truck or vehicle, since the rear wheels of the truck or vehicle are subject to minimum lateral displacement due to lateral deviations or changes in the course of the truck or vehicle in traversing the highway.

In order to compensate for rearward movements of the painting machine permitted by the shock-absorbing or cushioning spring 13 for the draw'bar thereof, the locking dog 89 which is engageable with one or another of the notches 84 in the segment 18 carried by the pmnting machine is slidable in the guide 8| (Fig. 11) fixed to the draw bar 65 and has a stem 84" connected to the releasing rod 83, a compression spring 84 encircling the stem and bearing at one end 5 against an adjusting screw 84 threaded in the guide and at its other end against a lug 84 on the locking dog, said spring acting'to yieldingly force the dog 89 forwardly and thereby hold it in engagement with the notch in the segment 18 10 as shown in Fig. 11 but permiting the dog to yield rearwardly with the segment when the painting machine to which the segment is at tached moves rearwardly, due to sudden or uneven pulling of the draw bar, the spring 84 how- 15 ever permitting the dog to be retracted and thereby disengaged from the segment when the releasing grip 82 is operated for that purpose, incident to a change in the angular setting of the painting machine relatively to the draw bar and thus alter the course to be steered along the highway by the painting machine.

In some instances it is desirable or necessary to cover the traffic guiding line with sand immediately after such line has been painted on the highway, the sand covering thus applied preventing tracking of the paint from the freshly painted trafiic line onto other portions of the highway. For this purpose, a sand-containing receptacle 94, preferably in the form of a hopper to contain a suitable quantity of sand, is provided, it being supported on wheels 95 which are preferably provided with pneumatic tires to absorb shocks due to unevenness in the road surface, these wheels being preferably fixed to an axle 96 which extends rotatably through the lower portion of the receptacle 94 and is provided with agitating arms 91 which project therefrom, so that rotation of the shaft 98 caused by the rolling of the supporting wheels 95 on the highway pavement will cause agitation of the sand in the receptacle and thereby insure uniform fiow of the same to the discharge opening 98 formed in the bottom thereof. In order to regulate the amount of sand discharged upon the painted line, a controlling valve 99 is mounted to slide across the discharge opening 98 so as to cover it more or less and thus determine the size of this opening, and the controlling slide may be provided with a rack bar I99 with which a pinion IN meshes, the pinion being supported on the hopper or receptacle 94 by a bearing bracket I92 and being connected by a universal joint I93 to an operating shaft I94, the latter having a handle I95 at its upper end for rotating it. The sanding device is provided with means for attaching it to the painting machine so that it will trail in the rear thereof and the sand will be deposited therefrom onto the tramc line painted on the highway. For this purpose, the sanding device is pro- 69 vided with a yoke I96 which is attached to the sides of the sand receptacle or hopper 94 and has its forward portion pivotally connected by the vertical pivot pin or bolt I91 to a bar 9'! which in turn is pivotally connected by horizontal pivot screws 31* to the rear cross member 31 of the painting machine, the pivot screws 3'I being for example rotatably fitted in down-turned ends of the bar 3! and removably threaded in plugs secured in the ends of the rear cross member 3'! 70 which may be tubular as shown. The vertical pivot I91 is located midway of the width of the painting machine and sanding device and the ver-' tical axis of the pivot I91 and the horizontal axis of the screws 31 are located between the axes of the pair of supporting wheels of the painting machine and the pair of supporting wheels of the sanding device so that the sanding device will trail behind the painting machine with its sand discharge opening 98 above the traffic line painted on the highway surface by the painting machine and the painting machine and sanding device may independently move vertically and thus accommodate any unevenness in the highway surface. The sanding device may conveniently occupy a position beneath the attendants seat 86 so that it will not interfere with the attendants control of the painting machine and the sanding device will be in a position where it may be controlled by the attendant occupying said seat.

The operation of a highway marker constructed as hereinbefore described is generally as follows:'--

Assuming the painting machine; and also the sanding device when such is used, to be attached to the laterally extending bar 64 on the inner or left hand side of the truck or vehicle, the latter is driven along the highway or the portion thereof to be painted with the trailic guiding line, so that the front right wheel of the vehicle is immediately adjacent to the right hand edge of the pavement of the highway, this being accomplished by the attendant occupying the auxiliary seat 6 and manipulating the auxiliary steering wheel 5.

Paint from the tanks I2 is supplied to the paint gun 48 through the flexible hose 20 and compressed air is supplied to the paint gun through the flexible hose 2 I. Assuming the disks 3| to be set at the proper distance apart by adjustment of the roller carrying posts 39, according to the width of the traflic guiding line being painted on the highway, the paint gun is operated to spray the paint onto that portion of the highway surface which is exposed between the lower peripheral edges of the disk 3| which are held in contact with the highway surface individually by the springs 32. The paint thus spread onto the highway surface will cover the area thereof exposed between the disks but the disks in contact with the highway surface at opposite sides of the paint gun will intercept any paint spreading beyond the exposed width of the highway surface, these disks thus defining sharply the edges of the painted strip and determining the width thereof in accordance with the setting or lateral spacing of the disks 3|. Since these disks are in rolling contact with the highway surface, they will revolve as the painting machine is drawn forwardly, and surplus paint adhering to the inner sides of the disks will be scraped therefrom by the branches of the trough 42 and such paint will be collected in the bucket or receptacle 41, splashing or picking up of surplus paint and spreading or dropping thereof upon the highway beyond the side edges of the painted lines thereon being thereby avoided.

When the traffic line is being painted on a straight portion of a highway, the draft bar 65 is set in its central position with respect to the locking segment 18, the supporting wheels 21 of the painting machine then steering the latter in a course parallel to that of the truck or vehicle, and the setting of the slide 66 at the proper position along the bar 64 will cause the painting machine to travel along the highway centrally of the width thereof. When a traflic line is to be painted on a curve in the highway, the draft bar 65 is swung toward or from the vehicle to the proper angle according to the direction of the curve and the degree or radius thereof, the consequent setting of the pivot I6 toward or from the vehicle compensating for the curve in the highway so that the traflic guiding line painted thereon by the painting machine will be located centrally of the widththereof. 5

When the sanding device is employed, it trails behind the painting machine and deposits a strip of sand upon the freshly painted line and thus avoids tracking of the paint therefrom until it has dried.
